Write a lambda expression that accepts two long arguments as a range borders and calculates (returns) production of all numbers in this range (inclusively). It's guaranteed that 0 <= left border <= right border. if left border == right border then the result is any border.
Solution format. Submit your lambda expression in any valid format with ; on the end.
Examples: (x, y) -> x + y; (x, y) -> { return x + y; };
